On the outskirts of Arvada, Colorado lies Innova-Park. What was supposed to be a fun way to advance science and robotics became one of the biggest financial failures in history. Now the park lays abandoned and ruined; breaking down day by day while the world moves on.  When a group of urban explorers go missing in the park, their manager hires Private Investigator Thomas Mori and former park employee Amory Harrmann to find them. But upon entering Innova-Park, the two come to find out that the park is occupied, and what lurks in its ruins wants to kill them.
